How to Install Copper Compression Connectors

This guide provides step-by-step instructions for properly installing copper compression connectors for electrical wiring.

Estimated time: 30m

Tools needed:

Wire strippers, Crimping tool, Multimeter

Supplies needed:

Copper compression connectors, Wire brush

  1. Strip the wire insulation

    Carefully strip the insulation from the conductor to a length that allows the stripped conductor to fill the barrel of the connector completely.

  2. Clean the conductor

    Use a wire brush to clean the stripped portion of the conductor, ensuring that any oxide films are removed.

  3. Insert the conductor into the connector

    Insert the cleaned and stripped conductor completely into the connector barrel, ensuring it is fully seated.

  4. Crimp the connector

    Using the appropriate crimping tool, crimp the connector securely according to the manufacturer's specifications.

  5. Verify the connection

    Use a multimeter to check the continuity and ensure a proper electrical connection has been made.
